Be sure that all the needed device drivers have been installed. For example, if you are using a
printer, you need a driver for that model printer.

Remove all bootable media (CD/DVD or USB device) from the system before turning it on.

If you have installed an operating system other than the factory-installed operating system,
check to be sure that it is supported on the system.

If the system has multiple video sources (embedded, PCI, or PCI-Express adapters) installed
(embedded video on some models only) and a single monitor, the monitor must be plugged into
the monitor connector on the source selected as the primary VGA adapter. During boot, the
other monitor connectors are disabled and if the monitor is connected into these ports, the
monitor will not function. You can select which source will be the default VGA source in
Computer Setup.

to the system board. You must disconnect the power cord from the power source before opening the
computer to prevent system board or component damage.
